What is Augument Reality | Types of AR |How AR works | Advantages and Disadvantages of AR | Application sectors
In this post we gained brief understanding about Augument Reality, how it works ? It’s various types ? It’s Advantages and Disadvantages , so let’s begin our jounery of learning.
What is AR ?
AR reality is computer technology that adds digital content onto live camera feed, making that digital content look as if it is part of the physical world around you.AR can provide a view of the real-time data flowing from products and allow users to control them by touchscreen, voice, or gesture.

Types of AR :
Marker-based: AR applications are triggered by specific physical images (markers) captured by the camera to position the digital content on top of it. A marker can be an object or a visual suchas logos, posters, or QR codes. The video below demonstrates a marker-based AR. The business card acts as a marker for the AR application which displays additional digital information after it encounters the card.
Markerless: Markerless AR does not depend on markers and lets users decide where to display the digital
content. Markerless AR applications rely on the camera, GPS, compass, and accelerometer of the device to gather information about the environment.
There are also different types of markerless AR technology:
Superimposition-based :AR detects the objects in the real world and partially or fully replaces their original view.
Projection-based : AR does not need a display device as it projects light onto a surface to display digital objects.
Location-based : AR provides augmentation in specific places. It uses the device’s GPS and compass to position the virtual object at a point of interest. Pokemon GO mobile game is a
popular example that uses location-based AR.
How it works ?
Augmented reality starts with a camera-equipped device—such as a smartphone, a tablet, or smart glasses—loaded with AR software. When a user points the device and looks at an object, the software recognizes it through computer vision technology, which analyzes the video stream. The device then downloads information about the object from the cloud, in much the same way that a web browser loads a page via a URL. A fundamental difference is that the AR information is presented in a 3-D “experience” superimposed on the object rather than in a 2-D page on a screen. What the user sees, then, is part real and part digital. AR can provide a view of the real-time data flowing from products and allow users to control them by touchscreen, voice, or gesture. For example, a user might touch a stop button on the digital graphic overlay within an AR experience—or simply say the word “stop”—to send a command via the cloud to a product. An operator using an AR headset to interact with a industrial robot might see superimposed data about the robot’s performance and gain access to its controls. As the user moves, the size and orientation of the AR display automatically adjust to the shifting context. New graphical or text information comes into view while other information passes out of view. In industrial settings, users in different roles, such as a machine operator and a maintenance technician, can look at the same object but be presented with different AR experiences that are tailored to their needs. A 3-D digital model that resides in the cloud—the object’s “digital twin”—serves as the bridge between the smart object and the AR. This model is created either by using computer-aided design, usually during product development, or by using technology that digitizes physical objects. The twin then collects information from the product, business systems, and external sources to reflect the product’s current reality. It is the vehicle through which the AR software accurately places and scales up-to-date information on the object.

Advantages of Augmented Reality (AR):
➨The AR system is highly interactive in nature and operates simultaneously with real time
environment.
➨It reduces line between real world and virtual world.
➨It enhances perceptions and interactions with the real world.
➨Due to its use in medical industry, life of patients have become safer. It helps in efficient
diagnosis of diseases and in early detection of them.
➨It can be used by anyone as per applications.
Disadvantages Of AR:
➨It is expensive to develop the AR technology based projects and to maintain it. Moreover production of AR based devices is costly.
➨Lack of privacy is a concern in AR based applications.
➨In AR, people are missing out on important moments.
➨Low performance level is a concern which needs to be addressed during testing process.
➨It requires basic learning to effectively use AR compliant devices.
Application Sectors :
Medical
Education
Real estate
IT
Retail
Manufacturing
This is brief description about Augument Reality how it works, advantages and disadvantages and it’s various applications. I hope this post helps you in your learning.
Thank you , Happy learning !!!
